[Dovecot] Maildir ignore
by Tomas Horacek 01 Oct '07

01 Oct '07

Hello there. I do like Dovecot so far, but ran into problem I cant seem to solve, maybe someone can point me into right direction please. I am running version 1.0.rc15 on CentOS 5 Linux i386 system, ext3 fs. The problem is I cant get the maildir: and :ignore to work together. Here is my SQL query, that includes the Quota field. # cat /etc/dovecot-sql.conf | grep -i quota user_query = SELECT maildir AS home, 901 AS uid, 901 AS gid, CONCAT('maildir:storage=', floor(IF(quota!=0, quota,-1)/1000), ':ignore=Trash') AS quota FROM mailbox WHERE username = '%u' AND active = '1' Even Dovecot agrees it seems correct. # cat /var/log/maillog | grep kaktus | grep quota\= | tail -n1 Sep 30 23:37:33 XXXXXX dovecot: auth(default): master out: USER 5 XXX(a)XXX.cz home=XXX uid=901 gid=901 quota=maildir:storage=1024:ignore=Trash I hope this is the correct way. Looking at IMAP communication with Wireshark, the server seems to ignore my settings. 118 uid copy 22 Trash\r\n 118 NO Quota exceeded\r\n Anyone can help me, please ? Thank you in advance. --- # dovecot -n # /etc/dovecot.conf listen: [*] ssl_ca_file: /etc/postfix/ssl/cacert.pem ssl_cert_file: /etc/postfix/ssl/smtpd.crt ssl_key_file: /etc/postfix/ssl/smtpd.key login_dir: /var/run/dovecot/login login_executable(default): /usr/libexec/dovecot/imap-login login_executable(imap): /usr/libexec/dovecot/imap-login login_executable(pop3): /usr/libexec/dovecot/pop3-login login_greeting: login_greeting_capability(default): yes login_greeting_capability(imap): yes login_greeting_capability(pop3): no first_valid_uid: 901 last_valid_uid: 901 mail_location: maildir:/srv/mail/%d/%n mail_executable(default): /usr/libexec/dovecot/imap mail_executable(imap): /usr/libexec/dovecot/imap mail_executable(pop3): /usr/libexec/dovecot/pop3 mail_plugins(default): quota imap_quota mail_plugins(imap): quota imap_quota mail_plugins(pop3): quota mail_plugin_dir(default): /usr/lib/dovecot/imap mail_plugin_dir(imap): /usr/lib/dovecot/imap mail_plugin_dir(pop3): /usr/lib/dovecot/pop3 auth default: mechanisms: plain login cram-md5 digest-md5 apop user: nobody verbose: yes debug: yes passdb: driver: sql args: /etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /etc/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail

When I drag n drop spam mail to SPAM folder, I get this error: Jun 11 17:58:46 sparrow dspam[28452]: Unable to open file for reading: /var/spool/dspam/data/local/mymail/mymail.sig/466d652f315451306914567.sig: No such file or directory mymail is user that runs dovecot transport (postfix config).

[Dovecot] dovecot-dspam plugin & virtual users
by Wicher Minnaard 30 Sep '07

30 Sep '07

Hi list, hi Johannes, I'm trying to use the dovecot-dspam plugin ( http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration ) with vpopmail's virtual users. All seems well, except for the fact that dspam should be called with '--user currentuser(a)currentdomain.com' at line 157 here: http://johannes.sipsolutions.net/Projects/dovecot-dspam-integration/beta7-c… For my needs, 'currentuser@currentdomain' could be taken as the login name I use for logging in to Dovecot. As I'm not a C-programmer by a long shot, I was wondering if one of you could help me use the bincimap-API to import the login name into a variable so I can use that variable to construct a suitable dspam-command. Hope this is possible! Regards, Wicher Minnaard

[Dovecot] dovecot dspam plugin using libdspam
by Andreas Schneider 30 Sep '07

30 Sep '07

Hi, I've found the dovecot dspam plugin and looked at the code. I forks and calls the dspam binary for every mail. I didn't like this behavior, so I've migrated it to use libdspam. The plugin still needs more love: * Use cmake instead of a Makefile * Make the spam folder configurable in the dovecot.conf * Code cleanup and more comments. Please test. Comments and patches are welcome ;) http://www.cynapses.org/tmp/dovecot-dspam-plugin-0.1.tar.gz Cheers, -- andreas -- http://www.cynapses.org/ - cybernetic synapses

[Dovecot] Problem with manually moving maildir files between folders
by Bill Landry 30 Sep '07

30 Sep '07

dovecot --version 1.1.beta1 With previous versions of Dovecot I could manually move maildir files between folders and the index would automatically update when entering the folder with Thunderbird. However, with 1.1.beta1, I am seeing the following when entering the folder, when attempting to rebuild the indexes via Thunderbird, or when attempting to force the download of all messages in the folder (this is with mail_debug = yes): Sep 30 09:05:55 mail dovecot: imap-login: Login: user=<bill(a)inetmsg.com>, method=PLAIN, rip=192.168.1.100, lip=192.168.1.37, TLS Sep 30 09:05:55 mail dovecot: IMAP(bill(a)inetmsg.com): Effective uid=1000, gid=1000, home=/var/spool/vmail/inetmsg.com/ Sep 30 09:05:55 mail dovecot: IMAP(bill(a)inetmsg.com): maildir: data=/var/spool/vmail/inetmsg.com/bill Sep 30 09:05:55 mail dovecot: IMAP(bill(a)inetmsg.com): maildir++: root=/var/spool/vmail/inetmsg.com/bill, index=, control=, inbox=/var/spool/vmail/inetmsg.com/bill Sep 30 09:05:58 mail dovecot: imap-login: Login: user=<bill(a)inetmsg.com>, method=PLAIN, rip=192.168.1.100, lip=192.168.1.37, TLS Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): Effective uid=1000, gid=1000, home=/var/spool/vmail/inetmsg.com/ Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): maildir: data=/var/spool/vmail/inetmsg.com/bill Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): maildir++: root=/var/spool/vmail/inetmsg.com/bill, index=, control=, inbox=/var/spool/vmail/inetmsg.com/bill Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): open(/var/spool/vmail/inetmsg.com/bill/.SURBL/cur/1190901367.M206487P27879V… failed: Permission denied Sep 30 09:05:58 mail dovecot: IMAP(bill(a)inetmsg.com): Disconnected: Internal error occurred.

by "Fábio M. Catunda" 30 Sep '07

30 Sep '07

Hi! Is there a way to log the file that have been copied when a person move it from a folder to another using mail_log? Actualy this is what I get in logfile: dovecot: 2007-09-27 15:15:33 Info: IMAP(user(a)mydomain.com): copy -> Spam: uid=101, msgid=<46FBC6C9.1060301(a)somedomain.com>, box=Dovecot What I would like to have is something like: dovecot: 2007-09-27 15:15:33 Info: IMAP(catunda(a)mydomain.com): copy -> Spam: uid=101, file=/cur/1190916950.P15981Q38M976125.mydomain.com:2,S, box=Dovecot I believe that its a pretty simple thing to do, but my C skills are null! Any help would be great. Thankz! !DSPAM:46fc21ce213771244520847!

[Dovecot] Subaddress Extension in sieve plugin
by Frank Behrens 30 Sep '07

30 Sep '07

Hello! With many MTAs it is possible to use a special form of adressing: subaddresses or "plussed addresses". For sendmail you can read some information on http://www.sendmail.org/m4/misc_features.html http://www.unix.org.ua/orelly/networking/sendmail/ch24_04.htm#SML2-CH-24-SE… In a sieve filter you can analyse these special detail values, the syntax is described in RFC3598 (http://tools.ietf.org/html/rfc3598) The current deliver with sieve plugin for dovecot seems to support this RFC, but has the detail information not available. If I use require ["subaddress", "fileinto", "reject"]; require "envelope"; if envelope :detail "to" "junk" { fileinto "junk"; } the rule is not triggered, because the detail information from envelope is not available. Deliver gets the user information only via command line switch "-d". I did not analyse the problem very deep, but I believe we should introduce a new command line parameter for deliver, so deliver can pass the detail information to the sieve plugin. With that parameter you are able to pass the detail information from sendmail to devecot's deliver in the same way procmail is handled (procmail uses -a parameter). To avoid confusion: deliver has already a parameter -m to specify a different mailbox. In the described case the mailbox should be determined by the sieve filter, not via command line parameter. Existing workaround: Because I need this functionality I wrote a quick (and dirty?) workaround. Sendmail does not call deliver directly, but a wrapper program, that adds an additional "Delivered-To" header line. So the detail information may be processed with if address :detail ["Delivered-to"] "junk" { but I would prefer to call deliver directly. What do you think, is it a useful extension and does it work?

[Dovecot] v1.1.beta1 POP3 delete problem
by arvids 30 Sep '07

30 Sep '07

Hello, POP3 server does not delete mails when user quits POP3 session, but only at the next login. It looks so - user logs in with USER and PASS commands, at this moment new messages are moved from /new to /cur maildir folder. Then messages are deleted with DELE command(before deleting there can be other POP3 commands) and the user quits session. The server says "+OK Logging out, messages deleted.", but in fact messages are not deleted from the disk and stays in /cur folder. And these messages are deleted only when user logs in next time. dovecot -n: # 1.1.beta1: /usr/local/dovecot/etc/dovecot.conf base_dir: /var/run/dovecot/ syslog_facility: local0 protocols: pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/dovecot/libexec/dovecot/pop3-login login_greeting: Server. login_process_per_connection: no login_process_size: 64 verbose_proctitle: yes first_valid_uid: 95 first_valid_gid: 95 mail_uid: 95 mail_gid: 95 mail_location: maildir:~/Maildir mail_debug: yes fsync_disable: yes mail_executable: /usr/local/dovecot/libexec/dovecot/pop3 mail_plugins: quota mail_plugin_dir: /usr/local/dovecot/lib/dovecot/pop3 pop3_enable_last: yes pop3_client_workarounds: outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login digest-md5 cram-md5 apop cache_size: 2048 cache_ttl: 28800 cache_negative_ttl: 60 user: doveauth verbose: yes debug: yes debug_passwords: yes passdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf userdb: driver: prefetch userdb: driver: sql args: /usr/local/dovecot/etc/dovecot-sql.conf socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vmail group: vmail plugin: quota: dict:::proxy:/var/run/dovecot/dict-server:quotadict dict: quotadict: mysql:/usr/local/dovecot/etc/dovecot-sql-dict-quota.conf Regards, Arvids

[Dovecot] v1.0 vs 1.1b re: Postfix and Dovecot LDA
by Jerry Yeager 30 Sep '07

30 Sep '07

In running the various 1.0.n versions of Dovecot's LDA with the instructions in the wiki for using LDA with Postfix [on OS X 10.4] things went well using the instructions as-is (no setuid problems). This changed in moving over to the 1.1 beta. The LDA refused to work failing with the error "setgroups() failed: Operation not permitted" as I mentioned in a previous message. After reading the exchange between Bill Cole and Rich Winkel and following up on this, it seems that the new 1.1b wants you to give the Deliver app specific setuid permission via: cd /path/to/where/dovecot's/deliver/is sudo chmod u+s deliver Then things worked as before. There was no need to give the group 's' permission nor to change ownership of deliver from the default root:staff or root:wheel or whomever... . The error message seems odd though. I am not sure if, overall, this means there is a problem in Dovecot 1.0.n or that things are being tightened up in 1.1b. Thanks Bill and Rich for the tip! Jerry Yeager
